'forni no part ot the present ini/'entierl` as theyY constitute7 ainong other features, the subject-matter et a separate application.

The cooling' chamber C comprises an elongated metallic casing` 11i, oic general rectangular construction7 except the entrance er d thereof, which is ohliquely arranged, as Wiil be hereinafter more i'ullj; described. The entire casing is of substantially a solid construction7 with the exception oif the entrance or forward end, which is also closed by a. door when the chamber is in operation. At its rear end 16, the casing` #l is provided with a` transverse shoulder 1 5 termed troni the end 16 adjacent to but removed 'from the bottoni 17 of jrhe casinga This shoulder constitutes a support tor the rear end et the cooling' or circulation plate designated generelli7 as l1 so that it may be readily renioved ifroin the casing when desired. @n each side of the bottoni 17, at yhe forward or entrance end oi the casing; le and adjacent to the Vveiticil side Walls of seid casino` is a support or projection 18 of a height equai to that oit the shoulder l5. r

a at

.inese supports 18 combine to support the forward end et the cooling` or circulating` plate P in a manner similar to the shoulder.

The cooling)- or circulation plate P is a unitaryv rectangular structure inade up ot a series ot abutting; interooinmunieating; ree-A tnngular tuhes 1,5% through which exeter or other cooling fluid is adapted to circulate. The tubes ot the plete l) are so arranged and held one against the other that when the plate is placed upon the shoulder 15 and the support-s or projections 18g it constitutes what may be called a secondary bottom ot the casing- 1e, resting parallel to and renioi'ed :troni the bottoni 17 thereo'h to create a chamber 2O thereunder.

To provide 'for the Huid .circulation through the plate l?, the side Walls of the units` or tubes i9 thereof? are pierced hy the openings 21 adjacent to their ends Whirh when the tubes or units 19 are assembled so communicate that the 'Huid entering ay tube must dow through the entire length thereof before it can pass into thenefrt edi aeent tube or unit. That is, the opening 21, when the tubes or units 19 lare assembled, are staggered, by having the openings 21 in one wall ot a tube at one end thereof, and in the opposite wall at the other end of the same tube. Hence, when tubes 19 are assembled, every other pair of abutting side walls of the tubes 19 will have registering and intercommunicating openings at one end of the plate l); while the remaining abutting walls will have registering and fintercommunicating openings at the other end ot the plate. lt is therefore apparent vthat the fluid enters one ot the tubes 19, flows therethrough, enters the next adjacent tube and flows throughout the length thereotbefore passing to the nextv adjacent tube, `and sothe flow continues :until the entire plated) has been traversed. 1 Thus, throughout its entire length and breadth the plate l) has a tree circulation and :flow of fluid designed to cool the plate and the contents oit receptacles resting thereon. .1 i

At the rear end oft one ot the extreme side tubes 19 and in .the underside thereotv is an intake opening-22, to which connected the pipe 23. This pipe 23 passes through the bottom 17 ofthe casing 14, as at 24, and is then coiled about the rear uprightsor stand ards 11 of thefframe F, extending 'from one standardor upright to .theothen thereby creat-ing the coil 25 exposed to the atmospheric temperature. The outer or treeend 2G ot the pipe 23 is connected to a source ot fluid supply, by means ol which a constant liow of fluid is maintained in lthe pipe 23, the coils 25 and the-plate l.

f The remaining extreme side tube 19 ot the plate P opposed to theside tube having the intake opening 22,*'is provided` inL the under side thereof with a discharge connection 27, which vlikewise passes through the bot-- tom 17 ot the casing `14, as at 28, where it extends from under said casing andl is provided with a faucet 29.' "Bytheproyision ofthe faucet 29 the llow through the :pipe 23 and plate P may be regulated, soas to adjust the temperature kot the water flowing through the plate inside the chamber to atmospheric temperature. f

lt is manifest that the fluid flowing through the pipe 23 is brought to atmospheric temperature by the coil 25 4before vit enters the plate I", and 'that receptacles, together with their contents will., when placed on said plate,fbe likewise brought to the atmospheric tei'npcratureby the v'luiifl [low ing through the plate. Hence, whether the receptacles and their contents are above or below the atmospheric temperature when they are placed upon thc plate l), their temperature vis quickly-brought `tothe atmospheric temperature by the flow and temperan ture of the fluid. Ashas been'pointed out, the entrance end said door.

top and the terminals of the side walls extend atan angle to the horizontal from the top to the bottom of the casing. This entire vend ot the casing is open and surrounded, on all sldesby the outstanding flange or bead 30, which rests in t-he oblique plane of' the entrance end of said casing. lt is upon this flange or bead 30 that the door 31 ot the casing 14 slides. The joint between the door 31 and the flange or bead 30 is ground to form an air-tight seal for the chamber when the door is closed. To provide jor the reciprocation ot the door 31 a guide rod secured to the top oit the casing 14, by means of a bushing 33, and extends upwardly in a plane parallel to the entrance end oit casing` and to the plane ot reciprocation of the door. -Fixed medially to the upper edge of the door 31 is abracket 34, which when said door is in its operative position, terminates adjacent to the bushing 33, where itis provided with a right angular, oriliced extension 35. The orifice of the extension 35 receives the lguide rod 32, so that said bracket by means ot `its extensions 35 may reciprocate alongsaid rod. The door 31 is provided with arknoh 36, by means'of which the door may be raised to move: the bracket and its extension 35 along the-'rod 32. r-irtter yreceptacles have been placed upon the plate vit-hin the casing 14, the door is returned to its operative or closed position, where it rests flush upon the flange or bead 30; the weight ol: the door on said flange or bead practically sealing the entrance of the casing. j In the plane of the plate P a platform 37, the utility,` function, and construction ot which forms no part hereof, trom which the receptacles are moved to the casing 14, where they rest upon the plate l?. To insure the ready passage of the receptacle trom the platform 37 and the plate l?, trans'er plate 38 is mounted on the studs 39 adjoining the forward end ot the plate P and rests in the plane of bothl said 'plate P and the plat-torni 37. The door when closedis positioned between the transfer plate and the platform 37 and the space between the latter-vis only sutlicient to permit ot thc recijn'ocation ot An air exhausting pipe 40 communicates with the interior oi. the casing 14 through the bushing 41 in the bottoni 17 thereof, and at its other end coi'inects with a vacuum pump (not shown). rlhus the air within the casing maybe exhausted, it desired, which not only aids considerably in the cooling, but also prevents vthe substances cooling from beine; surrounded by moist air.

As -a' further precaution against the moisture within the casing 14 the chamber 20 under the plate .P is provided, when desired, with the suitable receptacles 42, wbichmay Laia/iw contain drying agents such as calcium, chloride, potassium hydroxide, or sulphuric acid, all ot which are absorbents of moisture.

rlhe square tubular units of the plate li may be secured one against the other in any desirable manner, but it has been found that subjecting the plate to a. solder bath is the most ei'ective and practical.

lt will be clear trom the foregoing that the present invention can be used to operate upon substances the 'temperature oi" which is either below or above the temperature of the surrounding atmosphere, and in either event the temperature ot said substances will be made to conform to that ot the atmosphere. llt is also possible to circulate heated iuid through the pipe 23 and the circulation plate l), however, by applying heat to the coil or heating the fluid before enters trie pipe 23. However, the present function is to reduce the temperature or' heated substances to that oft the surrounding Latinos phere, and it is apparent that changes in the details of construction in the present invention can be made without departing from the spirit and-scope hereo'l.
